Head of Iran's Passive Defense Organization Brigadier General Gholamreza Jalali says the US is heavily engaged in an“economic warfare” against the Islamic Republic, vowing measures to foil such moves.

“Economic warfare is the main US threat against Iran,” Fars news agency quoted Brigadier General Gholamreza Jalali as saying on Friday.

Jalali made a reference to US-engineered sanctions against Iran, saying 80 percent of such measures are of “economic nature” and are aimed at laying an “economic siege” on the Islamic Republic.

“Washington has set up a center at the US Treasury Department, tasked with monitoring …and implementing the anti-Iran sanctions,” he pointed out.

Furthermore, “the center is designing newer and more developed sanction models” against the Islamic Republic, he added.

The Iranian official cast doubt on the efficiency of the US-pushed sanctions, adding that Washington's primary objective has been to cripple Iran's banking and financial systems, but the “plot has been foiled due to the country's prudent measures,” Jalali pointed out.

He referred to the Western states' efforts to curb Iran's economic interactions with its neighbors as another move to place embargo on the Islamic Republic.

In response, Iran's Passive Defense Organization continues to monitor the threats, identify the country's “weak spots,” and advise the executive bodies on how to counter the potential impacts of the West's restrictive measures, the official went on to say.

Following the adoption of the June 9 UN Security Council resolution against Iran, the US and the European Union imposed additional unilateral sanctions on the Islamic Republic over its nuclear program.

Tehran says the sanctions have further promoted the country's trade and made the economy resilient in the face of the embargo.
